Answer 1

Answer 2

If they are tangent, they are congruent meaning they have the same side.

Answer 3

wait, so Tangent means they are congruent? So it also means that x = 7?

Answer 4

is that \[1/3x\] or \[\frac{ 1 }{ 3 }x\]?

Answer 5

no but AB has to equal to 7 by solving for x

Answer 6

since BC is 7

Answer 7

I'm going to screenshot it give me a second

Answer 8

Since both lines are equal the function must be equal to each other.

Answer 9

so what do I have to do, to find x?

Answer 10

Yes. Is this what the question asked you to do?
Find x?

Answer 11

\[\frac{ 1 }{ 3}x+5=7\]
This is how you set them equal to each other. This is like pre algebra I think.

Answer 12

yes !
